If there was a parasite on one zoanthid colony, would not all be affected

I have grown a lot of zoos in the past, and I have had similar experiences. We made a frag from a healthy colony at another reefer's place one time. I brought it home where it grew like mad for awhile. Then it suddenly retracted, and no matter what I tried, it died off.

I made two frags from another reefer's colony. They too died off.

I have made hundreds of other frags, and sold them, and never had another problem. It remains a mystery to me.
